Guile 2.0.13:

  scheme@(guile-user)> (define (foo n)
                         (if (= n 0)
                             'done
                             (foo (1- n))))
  scheme@(guile-user)> ,tracepoint foo
  Trap 0: Tracepoint at #<procedure foo (n)>.
  scheme@(guile-user)> (foo 5)
  Trap 0: (foo 5)
  Trap 0: |  (foo 4)
  Trap 0: |  |  (foo 3)
  Trap 0: |  |  |  (foo 2)
  Trap 0: |  |  |  |  (foo 1)
  Trap 0: |  |  |  |  |  (foo 0)
  Trap 0: |  |  |  |  |  done
  Trap 0: |  |  |  |  done
  Trap 0: |  |  |  done
  Trap 0: |  |  done
  Trap 0: |  done
  Trap 0: done
  $2 = done
  scheme@(guile-user)> 

Guile 2.1.5 (via guile-next in guix):

  scheme@(guile-user)> (define (foo n)
                         (if (= n 0)
                             'done
                             (foo (1- n))))
  ... ... ... scheme@(guile-user)> 
  scheme@(guile-user)> ,tracepoint foo
  Trap 0: Tracepoint at #<procedure foo (n)>.
  scheme@(guile-user)> (foo 30)
  $1 = done

Likewise, ,break and etc do not work for me.
